add a reference in ur class file. using System.Configuration;

if your connection string is like this add name="conn1" connectionString="string1" ur access will be like this. string conn = ConfigurationManager.ConnectionStrings[conn1].ConnectionString;

I think you looking for TypeConverterAttribute and ExpandableObjectConverter. The following link shows how to do it. <a href="http://msdn.microsoft.com/en-us/library/aa302326.aspx"> <a href="http://msdn.microsoft.com/en-us/library/ayybcxe5.aspx">

Try [BrowsableAttribute(true)] above your property description

Use something like this.... private void Textbox__KeyDown( object sender_, KeyEventArgs args_ ) { if ( args_.KeyCode == Keys.Return ) { // Do whatever } }

The following code will give you the list of available versions. const string regLocation = "SOFTWARE\\Microsoft\\NET Framework Setup\\NDP"; RegistryKey masterKey = Registry.LocalMachine.OpenSubKey(regLocation); RegistryKey tempKey; string[] SubKeyNames = masterKey.GetSubKeyNames(); for( int i = 0 ; i < SubKeyNames.Length ; i++ ) {tempKey = Registry.LocalMachine.OpenSubKey(regLocation + "\\" + SubKeyNames[ i ]); MessageBox.Show(SubKeyNames[ i ]); MessageBox.Show("\tVersion = {0}", tempKey.GetValue("Version").ToString()); } Or you can check the currently user version using the following. MessageBox.Show(Environment.Version.ToString());

use browsable attribute. [BrowsableAttribute(true)]

I just tried using the same code that u gave and it seems to work fine for me. Can you give me the code for the control and also the code for ur form. It might help.

Do you have the Microsoft office interop assemblies installed and referenced?

The simplest thing is create a form and put all the controls(grids, labels, textboxes, etc) that you will be needing into that form. Now go to the class declaration(.cs file) where it says "public partial class Class1 : Form" and change it to "public partial class RSIntexPA : UserControl" Compile the project and generate it a dll. Now you can use your usercontrol via this dll anywhere.

You can override the Text property of the usercontrol so as to set the entered text into the label. Something like what is given below. [Browsable(true)] public override string Text { set { label1.Text = value; } } This will let you set the text in design time.

You can create objects of the items and then add the list of objects to the combo box.This way you can access the selected object from the datagridview cell.

Can you give us more detail on what you are looking at?
